What brings on asthma attacks?

Triggers for Asthma Attacks

Asthma attacks can be caused by a variety of environmental triggers, including:

* Allergens: These include pollen, dust mites, pet dander, mold, and certain foods.

* Irritants: These include smoke, chemical fumes, and air pollution.

* Exercise: Exercise can trigger asthma in some people. This is known as exercise-induced asthma (EIA).

* Cold air: Cold air can cause the airways to narrow, which can lead to an asthma attack.

* Stress: Stress can worsen asthma symptoms in some people.

In some cases, asthma attacks can be caused by a combination of triggers. For example, a person who is allergic to pollen may also have an asthma attack if they are exposed to smoke.
